Background

We are a small company with an internally hosted Exchange 2003. It receives email for 2 domains (the company was renamed a few years back). For the sake of argument, the domains are:

  • oldname.com
  • newname.com

We have moved newname.com to a hosted exchange service, and our DNS record is correctly routing emails. Our internal server still receives email for oldname.com, although we have asked our hosting company to accept emails for that domain.

Problem

My problem is that emails generated internally from monitoring software, printer, etc. are being caught by our (defunct) internal server and being delivered to the old mailboxes.

I believe that what is happening is that our internal exchange server considers itself to be the authoritive server for newname.com. I think it must be looking in active directory for a mailbox and delivering it internally without ever going outside.

Attempt to fix

I started to follow the article here: http://support.microsoft.com/kb/321721. I removed the SMTP recipient policy for newname.com, and added a dummy address and made it primary. I also answered yes for updating the associated emails. I then restarted the Microsoft Exchange Routing System and SMTP, but emails are still being routed internally.

Is there a way to force the exchange server to route all emails for the domain newname.com to the new hosted service?

While there certainly is a way to do this wouldn't the better solution be to reconfigure the devices/software to use your new email provider? You'd need to do this eventually anyway if you plan to decommission the old Exchange server and remove (uninstall) Exchange.

Thanks for the reply. Your suggestion is reasonable, but the system is older than my time here (I'm not an admin, just the most technical person in a small office). I worry that I might not think of everything that needs to be re-configured, and I hoped that re-configuring exchange would provide a good catch-all. –  Romski Dec 17 '12 at 2:43
